To @ZZ whom t may concern,.-

Be it known that I, HENRY H. VVATTs, a citi- Zen of the United States, residing in the city of Bakerseld, county of Kern, Stateof California, have invented certain new and useful its object to provide means of producing an approximately complete combustion of crude oils in an economical and handy manner.

. My object is accomplished by meansillustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my burner, showing the couplingl for pipe to oil-supply, coupling 2 for pipe to steam or compressedair pipe, and combustion end 3; Fig. 2, 'alongitudinal section of Fig. l; Figs. 3. and I and 5, details of parts shown in Fig. 2. Similar figures refer to similar parts throughout the drawings.

Referring to Fig. 2, the oil to be burned is admitted at l, flows into and ills the space between l and coupling 4;, in which it is held by a valve 5, controlled by theihagnd-lever 6, Fig. 1, through the forked rody 7. Within this space thus made bythe outer pipe is a smallerv inner p1pe'8, havlngan openingjQ communi-` eating with a source of steam or air supply.

When steam is used, it is therefore surrounded by the oil in the space between the opening 2 andthe valve 5, said space thus servingV as a heating-chamber and obviating the need or expediency of warming the oil outside the burner. The valve 5 is adjusted to permit a flow of oil adequate to the demand for coinbustion which enters the space 9 and iiows to the entrance of the mixing-nozzle l0. The inner tube is bent, as shown at 9, Fig. 2, and that part of the outer tube which the end of said inner tube approaches normally occupies the position of a licor, being adjustedto remain lower than the other parts, so that the oil droppinginto the space marked 9, Fig. 2,v

runs along said floor and is readily sprayed by the force of the fluid from the inner pipe 8. The weight of the oil brings it to the botthe depressed or bent portion.

tom of the burner, and an important feature of my invention is the bringing of the spraying means near the bottom and not near the center or top. The bent portionof said inner tube is hereinafter designated indilferently as AV blast from said steam-pipe tends to pick up and blow into said mixing-nozzle particles of oil off the floor of the burner.' In the mixingnozzle a separable spiral mixer, Fig. 5,`is provided which gives the mixed steam and vapor a whirling motion under the influence of the steams force, thus causing a thorough mixing thereof. The object of the depressed portion of the pipe 8 is to form thereof an atomizer, tending to transmit into the mixingchamber only the vapor of the eiland not its liquid.

After mixture in the nozzle l0 the vapor is emitted from the burner-holes-S, where it is ignited.

It will be noted by reference to the drawings that my burner does not operate after the manner of a nena contracte, nor is its object to produce an inrush of atmospheric air at or near the atomizing-point. The atomizer simply picks up the particles ofthe oil and blows them into the mixing-nozzle, Where the mixing process is completed. v

Steam is used for the atomizing process where the oilis not specially warmed before being introduced into the burner. Where special apparatus. is applied outside the burner to warm the oil, I use air in the pipe 8, Fig. 2. The reason I use the steam in the inner tube 'is that by so doing I make the burner act automatically in holding the steam-pressure in the boiler up to a certain point and no higher or lower. As shown, valve 5 is a simple handoperated valve and may be adjusted to allow greater or less opening for vthe oil How. When the valve-opening is large, a great pressure of steam in chamber 9 acting directly on the oil in the opening will tend to hold back.

its flow, and when the valve-opening is small a lower pressure of steam in said chamber will stop the flow of said oil. The steam acts directly against the oil and not by moving the said valve. Therefore the said valve may be adjusted to any desired position for regulat- IOO ing the ioW of oil, said iiow stopping when the pressure reaches the value for which said valve is adjusted and beginning again when velop Conforming to its spiral shape.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. An oil-,burner comprising an oilreoeiving chamber controlled by a valve, an inner steam-pipe running through said chamber and acting both as an atomizer and as means of conveying pressure to the oil in said valveopening whereby the How of oil is regulated, a mixing-nozzle having a separable interior spiral piece adapted to give spiral motion to the atomized oil and steam under the pressure of steam from said steam-pipe, and a burnerhole in said nozzle.

2. An oil-burner having an oil-chamber Controlled by avalve, asteam-pipe within said chamber extending therethrough and having adepressed portion adapted to cause the steam therefrom to piek up and atomize the oil emitted from said oil-chamber, a mixing-nozzle, and a burner-hole in said nozzle.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
